To all wlw/m t may concern.'

Be it known that I, ANDREW J. HOLMES, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of lVashington, have invented a certain new and useful Improvement in lFinding Mechanism, of which the following is a speciication.

My invention relates to improvements in coil winding mechanism and the object of my invention is to provide a mechanism for winding coils on a plurality of cores which are integrally connected on their ends to form a unitary structure and a continuous magnetic circuit.

Another object is to provide a mechanism for winding coils on a Y lurality of integrally connected cores embo ying novel actuating means for rotating the sleeve of the said coils in each of said cores during the winding of the coils thereon.

A further object is to provide mechanism for winding coils on a plurality of integrally connected cores embodying novel adjustable supporting means for said cores.

A still further object is to provide a mechanism for winding coils on a plurality of integrally connected cores embodying novel indicating means to register the number of turns on each of the said cores dur-- ing the winding of the coils thereon.

still further object is to provide a mechanism for winding coils on a plurality of integrally connected cores embodying novel elect-rically operated Y signal alarm means adapted to be actuated when the required number of turns have been wound on each of said cores.

A still further object is to provide a mechanism for winding coils on a plurality of integrally connected cores embodying novel clamping means adapted to clamp said mechanism in any desired angular position.

A still further object is to provide a mechanism for winding coils on a plurality of integrally connected cores embodying simplicity, durability, strength and economy in construction, that is positive andeficient in operation, and that will not readily get out of order.

Nith the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination, adaptation and arrangement of and claimed,

vbeing in section parte hereinafter `described- I accomplish these objects by devices illustrated in the wherein- Figure 1 is a'top plan view of a winding mechanism embodying the features of myI invention and villustrating an enclosed or double core operatively positioned therein for winding a coil on one of the core portions; f

Referring to the drawings, throughout which like reference numeralsr indicate like parts, the numerals 10,511 and'lQ indicate) the base brackets or bearing blocks `ofmy winding mechanism, which base brackets are disposed in .alignment and-in spaced apart relation with respect to each other, as shown more clearly `in Fig. 1,' the said base brackets being adapted to be iiXedly secured, in any yvlell known manner, to a work bench or-the 1re. 1 Journalled for rotation within the bosses Vl?) formed on the base brackets 10, -11 and 12 is a shaft 14,. which shaft is adapted to extend outwardly from the base bracket 10 and is provided at a point adjacent its outer or` forward end with a crank handle 15 which is adapted to be Xedly secured*` thereto. j y

Fixedly secured to the shaft 14 adjacent the inner side of the base bracket 10 isa discl 16, which disc is provided on its periphery with spur gear teeth 17, and a peripheral flange 18, which flange is disposed in spaced y* apart relation on the periphery of said disc to'thus form an annular groove 19.

Mounted for oscillatory movement on the disc 16 is a work holder 2O which is formed in the shape substantially as shown and which comprises a lower half 21 and an upper half 22, which halves are hingedly connected at one of their ends thereof by a hinge pin 23 and at the other or opposite end are adapted to be detachably secured or clamped by a machine screw 24 or any other suitable or desired manner.

The halves 21 and 22 are each provided with a semi-circular opening 25 which openings are formed of the size and shape to lit the periphery of the disc 16 as shown more clearly in Fig. 4. Each of said semi-circular openings being provided with an inwardly projecting semi-circular flange 26 which is adapted to normally seat in the annular groove 19 formed in the disc 16, when the work holder 2O is in a closed position.

Semi-circular openings 27 of substantially the size and shape as the semi-circular openings 26 are also formed and provided in each of the halves 21 and 22, which openings 27 are disposed in spaced apart relation with respect to the openings 26 substantially as shown in Fig. 5.

Concentrically disposed in the semi-circular openings 27 for rotation therein is an annular disc 28, which disc comprises a lower half 29, and an upper half 30, each of the halves 29 and 30 are provided with spur gear teeth 31, and a peripheral fiange 32 which flange is disposed in spaced apart relation with respect to the teeth 31 to thus form an annular groove 33.

The spur gear teeth 31 of the disc 28 are adapted to securely mesh with the spur gear teeth 17 of the disc 16, as shown more clearly in Figs. 2, 5 and 8.

The semi-circular openings 27 are each provided with an inwardly projecting semicircular flange 34, which flange is adapted to movably seat in the annular groove 33 when the work holder 20 is in a closed position,

The halves 29 and 30 of the annular disc 28 when the same are operatively disposed in juxtaposition as shown in Fig. 5, form a cylindrical seat or base 35 which seat is adapted to receive and support one end of a cylindrical core 36 which cylindrical core forms part of a double integrally formed hollow core member 37, the said core member may be formed or provided with two or more cylindrical cores as desired.

To support the rear or opposite end of the core member 37 l have provided an arm 38 and an angularly adjustable bracket or rest 39 which arm and bracket are formed substantially as shown.

The arm 38 is mounted for oscillatory movement on the shaft 14 at a point on said shaft adjacent the base bracket 11, as shown more clearly in Fig. 1, and to prevent axial movement of said arm 38 on the shaft 14 I have provided a collar 38a which is adapted l0 V- to abut the said arm and to be fiXedly secured to said shaft 14.

A boss 40 is provided on the outer end of the arm 38, which boss is provided on its inner face with radial serrations 41 which are adapted to normally engage similarly formed radial serrations 42 on the outer face of the boss 43 of the adjustable bracket 39.

To retain the serrations 41 and 42 in engagment l have provided a hollow bolt of threaded pin 44 which is concentrically disposed in the bosses 40 and 43 as shown.

in adjusting screw 45 is threadably disposed in the outer end of the adjustable bracket 39, and is adapted to normally abut or engage the outer side of the core member 37 at a point adjacent the rear end thereof.

To prevent longitudinal movement of the core member 37 when the latter is operatively disposed as shown in Figs. 1 and 2, l have provided adjusting screws 46 one of which screws is adapted to be threadably engaged in the hollow bolt 44 and is adapted to abut or engage the rear end of the core member 37 at a point substantially in concentric alignment with the axis of the core 36 on which the coil is being wound while the other of said adjusting screws 46 is threadabljv disposed in a boss 47 of an arm 48, the said last named adjusting screw being` adapted to abut or engage the forward end of the core member 37 at a point substantially in concentric alignment with the axis of said core 36.

The arm 48 is mounted for angular adjustment in a vertical plane on the shaft 14 being retained in any desired angular position by a set screw 49. lt will be apparent by referring to Fig. 1 that the arm 48 is also adapted for axial adjustment on the shaft 14.

To positively retain and maintain the aXis of the cylindrical seat formed in the annular disc 28 which is disposed for rotation in the work holder 2O in correct alignment at all times with respect to the axes of the bosses 40 and 43 formed respectively on the arm 38 and the adjustable bracket 39 I have provided a, tie rod or shaft 50 which is adapted to be iixedly secured at one end in the lower half 21 of the work holder 20 while the opposite or rear end of said rod is adapted to be fixedly secured in the lower portion of the arm 38 as shown more clearly in Figs. 3 and 4.

As hereinbefore mentioned and described the work holder 20 and the arm 38 are each mounted and adapted for oscillatory movement as a unit with respect to the shaft 14 for the purpose of obtaining selective angular positions for said holder and arm in order to increase the scope and utility of my winding mechanism to enable the latter to handle core members 0f varying sizes and at points adjacent the bossesv as shown inl Fig. 4. The said cams being adaptedto normally engage and clamp the respective peripheries of the arcuate portions formed on the underside of the half 21 of' the work holder 20 and the arm 38 as shown in Figs. 3 and 5.

The indicator mechanism for my winding machine comprises a worm 56, a worm wheel 57, a driven shaft 58, a bevel pinion 59, a bevel gear 60, an arbor or spindle 61, a dial plate 62 and a hand or pointer 63.

The worm 56 is adapted to be mounted on the shaft 14 at a point between the base brackets 11 and 12 as shown in Fig. 1.

The worm wheel 57 which is adapted to normally mesh with the wormy 56 and to be interposed between bearings or bosses 64, which bearings may be formed integral with the base bracket 12 as shown.

The worm wheel 57 is also adapted to be mounted on the lower end of the driven shaft 58 which shafty 58 is adapted to lbe journalled in an integral boss formed on an upright extension 66 n of the base bracket 11.

Fixedly secured to the upper end of the driven shaft 58 is the bevel pinion 59 which is adapted to normally mesh with the bevel gear 60, which bevel gear 60 is adapted to be fixedly secured to thev rear'- end of the arbor 61.

The arbor 61 is adapted to be journalled for rotation in a boss 67 formed on the upper end of the upright extension 66, the forward end of the said arbor 61 is further adapted to project outwardly from said boss 67 vand is provided on said forward end with a threaded portion 68. i Y

, The dial plate 62 is adapted to be disposed in concentric alignment with respect to the arbor 61 the said dial plate being supported in its proper operative position on said arbor and secured against rotation by counter-sunk screws .69 threadably engaged in an integral boss 66al formed on the forward face ofthe `extension 66 as shown in Fig. 7.

The hand 63 is freely mounted on the threadedportion 68 of the arbor 61 and is adapted to be normally clamped to said arbor by` a thumb 41119.79, which thumb mit is threadably engaged on the threaded portion 68 and is adapted to secure and clamp the said hand y63, against an integral collar formed on the said arbor 61 to thus positively insure said hand turning with said arbor when thus clamped, however, if it is desired to return the hand 63 to zero the thumb nut 7 O'is unscrewed and the hand 63 returned tothe position shown in Fig. 2 in which position said hand is adapted to abut a stop pin 71. f y

The front or forward face of the dial plate 62 may be provided on its edge portion with suitable graduations 72, as shown in Fig. 2, which graduations in conjunction with the hand 63 serve to indicate the number of turns wound upon the core 36 at any `74 and a battery 75.

rThe pointer 73 may be formed of insulated material if desired and ismounted on a sleeve 76 of insulated material which sleeve is disposed for selectiveadjustment in a circular slot 77 formed in the dial plate 62 as shown in Fig. 2. A binding post78 is concentrically disposed inthe sleeve 76, said binding post 78 is provided on its forward end with a contact button 79 which is disposed in the path of the hand 63 which hand is adapted to contact therewith when the required number of turns have beenwound on the core 36.

A circuit wire 80 connects the binding post 78 with a binding post 81 of the bell 74, while the other binding,v post 82 of the bell 7 4 is connected by a circuit wire 83 to one side of the battery 75. yThe other or opposite side of the battery 75 is connected by a ground wire 84 to a binding post 85 attached to the upright extension 66 as shown in Fig. 2. f

In the operation ofmy winding mechanism when it is desired to form or wind` a coil on one` of the cores 36 of the core member 37 the work holder 20 is opened and the upper half 22 of the said holder is swung back substantially to the position shown in the dot and dash lines lin Fig. 2, the upper halt1 30 of the annular disc 28 is then removed 'at which time the holder 20 is ready to receive the core member 37.

The hand 63 of the indicator mechanism lis set at zero and clamped to the arbor 61, the pointer 73 is next set at the graduation representing the number of turns desired which determines the size ofthe coil to be wound. f

The work holder 20 andthe arm 38 are angularly adjusted and clamped in position to @Determ to the tyrel .0f @Ore member 37 ico to be operated upon, the adjustable bracket 39 is also set relative to the arm 38 and the arm i8 adjusted to the desired angular position for the same reason and purpose.

The operator then takes the core member 37 to be operated upon and places a split core or sleeve 86 about the core 36, which split core is formed of insulated material, such as fibre, which has been previously treated to render the same more eflicient as an insulator. V

The core member 37 is then ready to be operatively disposed in the winding mechanism and to be adjustably secured in position through the medium of t-he adjusting screws 4:5 and 4:6.

The upper half 80 of the annular disc 28 is then placed in juxtaposition relating to the lower half Q9 of the disc, the upper half 22 of the work holder 2O is then swung back to its operative position and the machine screw 24e screwed into place to clamp said upper half 22 in position. at which time the inwardly directed radially disposed pins 87 of the annular disc 28 pierce the cylindrical wall of the split core 86 at a point adjacent to the end thereof to thus provide a positive driving connection between said annular disc 28 and the split core 86.

The operator neXt selects the insulated wire of the proper size for the type of coil desired and inserts the end of the said wire through a notch 90 formed in the upper half 80 of the annular disc 28, said wire being inserted from the inner side of said disc in a forward direction a suiicient distance to permit said end. 89 being bent upwardly and disposed in an arcuate groove 91 formed in the face of said upper half 30 to thus positively retain the said end against movement during the rotation of the split core 86 and the winding of the coil thereon, as shown more clearly in Fig. 8.

rlhe shaft 14 is then rotated by the operator through the medium of the crank handle l5, the disk 16 being iixedly secured to the shaft 14 is rotated therewith and the spur gear teeth 17 of said disc 16 meshing with the spur gear teeth 31 of the annular disc 28 rotates the last named disc which in turn rotates the split core 86 to wind the insulated wire 88 thereon as shown in dot and dash lines in Fig. 1.

The operator rotates the shaft 14- with his right hand while with his left hand he guides the insulated wire during the winding operation.

When one layer of the insulated wire is wound upon the split core 86 said layer is coated with vitreX or other suitable insulating compound and another layer is wound upon said first named layer which when completed is also coated with vitrex this operation is repeated till such time as the required number of layers or turns have been obtained. at which time the hand 63 has been moved through its arcuate p'ath by its associated mechanism to the point where it contacts with the button 7 9 of the pointer 7 3 to thus close the circuit of the bell 74 and ring the same to warn or notify the operator that the necessary or required number of coils have been obtained to complete the coil.

The wire 88 is then cut to thus leave a free end or terminal of suitable length to permit of proper electrical connection being made with the coil wound upon the adjacent core 36 as will be readily understood.

The core member 37 is removed from the winding mechanism and the last layer of the coil wound upon the `split core 86 is coated with vitreX to present a smooth and nished appearance.

The foregoing operation is repeated in winding' a coil upon the other or adjacent core 36 which when completed is connected in series byone of its terminals of the first named coil.

The core member 87 when the coils have been completed and coated as hereinbefore described is then placed in an oven to dry after which cover plates are attached to said core ymember 37 to form a casing at which time said hollow core member is ready for installation as a water heater.

If desired ank electrically operated lock may be substituted for the signal alarm mechanism shown which lock will be actuated when the desired number of turns are obtained to thus lock the mechanism against further operation till the same has been reset.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation of my winding mechanism will be readily apparent to those skilled in the art to which my invention pertains. to thus enable those so skilled to con- 110 struct and operate the same, but, while I have shown and described the construction and operation of a winding mechanism embodying the features and principles of my invention, which I now consider to be the 115 best embodiment thereof, which mechanism is adapted to wind coils on a plurality 'of integral enclosed cores, I desire to have it understood that the winding mechanism shown e is merely illustrative and such changes may 120 be made when desired as are within the scope of my invention.
